Hey that chinese smart card dognel just arrived to the europian market. So its new here Actually, I was comparing the new technology with the old dongle technologies. Im not telling that its the best protection. But its something requires more than medium skills. I dont believe that generic emulators will be out (as crackers did for HASP4 for example). That RSA public/private (private stored inside the smart card) will bring lot of troubles to developers and will take long time to study and analyze that thing. Im almost sure that the cracker must have at least good skills on cryptography to prevent (or remove) this protection.
